The measurement of a diamond’s weight is known as the Carat.

Most gemstones are weighed in carats. The word Carat originates from times when diamonds and gold were weighed in comparison to carob seeds. We now refer to a diamond’s weight as Carat indicated by “ct”. One carat is equivalent to 200 milligrams or 0.2grams. Each Carat is divided into 100 points. You will often see diamonds referred to in this manner. For example, a diamond weighing 0.50ct may also be labeled as 50 points.

The Carat weight of a diamond does not reflect the actual size of the diamond. Many diamonds of the same Carat weight can look very different when placed side by side.

Why is it then that not all 1ct diamonds have the same diameter or appear to be the same size? Read more
